says scheme chairman Robert Humphreys.
Speaking at the Responsible Drinks Retailing conference , Humphreys said there are "pockets of resistance" to the Proof of Age Standards Scheme with some retailers only accepting driving licences or passports as valid forms of ID.
He said: "The time has come when we have to stand up for the young people who are entitled to their legal rights. If they have gone to the lengths of getting the card they should be allowed to use it."
Humphreys said the PASS scheme was originally considered a stop-gap in the run-up to national ID cards being produced, but
attitudes had changed.
"Increasingly, senior police and Trading Standards are moving away from recommending a passport as a good thing to carry around on a night out," he said. "The costs and hassle of losing your passport on a night out are huge and it will be worse for an ID card.
